I'm not clear on the licensing here. Are all files under the "illustrio license", and why does the summary that pops up seem to say something different than the detailed license text? I would be much more comfortable with a standard license being used - say, the Creative Commons licenses. At least let users filter their search by license terms, unless they're all under the same terms in which case that should be clearer.<p>I like the idea of being able to customize, but is that simply changing the colors? Or is it the ability to commission edits to the work? If it's just color changes I have trouble seeing the value; if it's substantial edits to the work then the pricing looks too low and the license terms are too restrictive.<p>Basically, what does this offer me that the Noun Project doesn't, except far more restrictive licensing terms?
